Breast cancer is a significant health issue affecting both women and men, though it is more common in women. The causes of breast cancer are complex, involving a mix of genetic, hormonal, and environmental factors. Genetics, family history, and excess exposure to the female hormone estrogen all play roles in elevating risk. Estrogen, a hormone vital for female reproductive health, can increase breast cancer risk when exposure is excessive. This overexposure can occur from hormonal birth control, acne medications, and treatments for menopause symptoms.
While we can’t change certain risk factors, such as age or genetics, some preventive measures may reduce breast cancer risk. These include breastfeeding, staying physically active, maintaining a healthy diet, and getting regular checkups and screenings. The American Cancer Society recommends women start yearly mammograms at age 40. However, women with a strong family history or other risk factors may benefit from earlier screening as their healthcare provider recommends.
The Benefits of Breastfeeding for Breast Cancer Prevention
Breastfeeding has numerous benefits for both mother and child. For mothers, breastfeeding not only supports postpartum health but is also associated with a reduced risk of breast cancer. During lactation, a woman’s hormonal environment shifts, which can help delay the return of menstruation, ultimately lowering estrogen levels over time. This reduction in estrogen exposure can contribute to a decreased risk of developing breast cancer later in life. Moreover, breastfeeding promotes the shedding of breast tissue, which may help remove cells with potential DNA damage, thereby lowering cancer risk.
Breastfeeding and other lifestyle changes like physical activity and balanced nutrition form part of a holistic approach to reducing breast cancer risk and promoting long-term health.
